IP68 ATEX EC Fans – New Product

IP68-ATEX rated EC fans grant protection in explosive gas atmospheres while also providing significant cost and energy savings. When employed in Zone 2 applications, ATEX fans eradicate the potential of a motor spark and explosion making them the leading choice for use around flammable gases. With the added IP68-rating, these fans effectively protect against dust and can also be submerged in water of depths up to three meters.
